Description: 在3GPP系统中，初始小区搜索包含两步，这两步要用到主同步信号和辅同步信号。这篇文章介绍了一种辅同步信号检测的方法。-In 3GPP Long Term Evolution (LTE) system,initial cell search procedure comprises two steps using primary
synchronization signal (PSS) and secondary synchronization
signal (SSS). This paper presents SSS detection method for
second step of initial cell search. In general, coherent detection
using estimated channel frequency response (CFR) at PSS is
used for SSS detection, but performance degradation is occurred
by difference of channel between PSS and SSS in time division
duplex (TDD) mode. Thus we propose non-coherent detection
using partial correlation and differential correlation. Moreover,
we consider cyclic-prefix (CP) detection algorithm that uses CP
and its repetition part of data symbol, and we investigate
influence of CP detection in SSS detection process.

the downlink access. This process is called the initial cell search.In this paper all the procedures of synchronization and initial cell search are specified. An innovative
processing algorithm for PSS, including the theoretical
analysis and deduction, is provided. Most important of all, the proposed scheme is able to evaluate the integer
carrier frequency offset (ICFO) more accurately and improve the detection error rate effectively.
